Remove torque converter

Position transmission vertically.
Fit grab handles (065) to torque converter.
Remove torque converter without tilting.
1. 4.1 If there are metal shavings in transmission oil pan, drain transmission oil from torque converter through a clean cloth.
  If there are metal shavings in the cloth: replace the torque converter as any remaining metal shavings will damage the transmission.
2. 4.2 If transmission oil is burnt or interspersed with abrasive particles: Rinse torque converter, oil cooling lines and oil cooler.

Install torque converter
Insert torque converter carefully without tilting.
Do not use force, otherwise the axial end stop of the torque converter will be irreparably damaged.

When doing so, move the torque converter back and forth until the drive spigots of the oil pump engage in the disengagement shift tubes of the torque converter.
Apply a little multi-purpose paste to journal (96).

Check that torque converter is seated correctly

An incorrectly inserted torque converter will be damaged when the transmission is installed, and will cause damage to the oil pump.

Place parallel gauge (01) on flange of transmission housing.
Using depth gauge, measure difference dimension (D1) between parallel gauge (01) and bolt flange of torque converter.
Add measured difference dimension (D1) and specified distance dimension (D2) together.
If the torque converter is inserted correctly, the sum (D1+D2) corresponds to the thickness (D3) of the parallel gauge (01): D1+ D2= D3.

If D1+ D2 does not equal D3: remove and insert the torque converter again and check whether it is seated correctly.
Detach grab handles special tool (065) from torque converter.
